A. Transportation plans adopted after January 1, 1997 in serious, severe or extreme ozone non-attainment areas and in serious CO nonattainment areas. If the metropolitan planning area contains an urbanized area population greater than 200,000, the transportation plan shall specifically describe the transportation system envisioned for certain future years which shall be called horizon years.
(1) The MPO, in developing the
transportation plan in consultation with the affected agencies identified in
Paragraph (1) of Subsection D of 20.11.3.105 NMAC, may choose any years to be
horizon years, subject to the following restrictions
(a) horizon years may be no more than 10
years apart;
(b) the first horizon
year may be no more than 10 years from the base year used to validate the
transportation demand planning model;
(c) the attainment year must be a horizon
year if it is in the time frame of the transportation plan and conformity
determination;
(d) the last year of
the transportation plan's forecast period shall be a horizon year
and
(e) if the time frame of the
conformity determination has been shortened under Subsection D of 20.11.3 NMAC
the last year of the time frame of the conformity determination must be a
horizon year.
(2) For
these horizon years: (a) the transportation
plan shall quantify and document the demographic and employment factors
influencing expected transportation demand, including land use forecasts, in
accordance with implementation plan provisions and the consultation
requirements specified by 20.11.3.105 NMAC;
(b) the highway and transit system shall be
described in terms of the regionally significant additions or modifications to
the existing transportation network which the transportation plan envisions to
be operational in the horizon years; additions and modifications to the highway
network shall be sufficiently identified to indicate intersections with
existing regionally significant facilities, and to determine their effect on
route options between transportation analysis zones; each added or modified
highway segment shall also be sufficiently identified in terms of its design
concept and design scope to allow modeling of travel times under various
traffic volumes, consistent with the modeling methods for area-wide...
